"His wife rang probably about 9.30am and said ‘look, Ray's cutting this tree up, I don't know if he can manage it all by himself’," he said.

"I said ‘look, I'll get down there when I can’, but I couldn't get through the road here. Maybe I felt a bit guilty that I couldn't get down there."

This afternoon, the Bureau of Meteorology (BoM) issued a severe weather warning for Adelaide and other southern parts of the state.

Residents have been urged to prepare for more damaging winds and heavy rain this evening, with the wild weather expected to continue until sunrise tomorrow, the BoM said.

This afternoon, the State Emergency Service said it had received more than 500 calls for assistance, mostly for fallen trees and other minor damage, including one incident where a man was rescued from a caravan which was tipped on its side.

At one stage, more than 13,000 properties were without power, but SA Power Networks said it expected to restore most services by late today.

The BoM said while conditions had eased throughout today, another vigorous cold front was expected to move through SA tonight and into tomorrow morning, bringing strong winds, heavy rain and possible thunderstorms.

A flood watch has also been issued for the Mt Lofty Ranges, with falls of up to 80mm expected.

Bureau of Meteorology acting regional director John Nairn said the worst of the weather was expected overnight and early tomorrow.

Forecasters expect Adelaide may have a top temperature of just 11C tomorrow, with up to 25mm of rain.

The damaging winds that occurred through the Mount Lofty Ranges earlier today are now easing, however there remains a chance of further wind gusts of 80-90 km/h over the next couple of hours.

Northwesterly winds are then expected to strengthen again this evening as a vigorous cold front approaches from the west, and shift southwesterly overnight and during Tuesday morning as the front moves over the south of the State.

Damaging winds, with gusts in excess of 90 km/h, are forecast in the warning area from this evening and are most likely associated with showers and thunderstorms or near the coast and over elevated areas.

Strong to gale force winds, averaging 50-65 km/h, are also possible near the coast and over higher ground within the warning area from this evening.

Heavy showers and thunderstorms may also lead to flash flooding over Adelaide and the Mount Lofty Ranges, from this evening until sunrise Tuesday morning.

Strathalbyn observed a wind gust of 104 km/h at 7 am this morning and Mount Crawford observed gusts of 93 km/h at 11:30 am this morning and at 1 pm this afternoon.

There have been widespread reports of trees down and property damage through the Mount Lofty Ranges.

The State Emergency Service advises that people should:

* Move vehicles under cover or away from trees;

* Secure or put away loose items around your property.

* Don't drive, ride or walk through flood water;

* Keep clear of creeks and storm drains;

* Stay indoors, away from windows, while conditions are severe.

The next warning is due to be issued by 6:55 pm.
